         NOW, THEREFORE, in consideration of the mutual promises, covenants,
agreements, representations and warranties hereinafter set forth and set
forth in the Merger Agreement and other good and valuable consideration, the
receipt, adequacy and sufficiency of which is hereby acknowledged, all

         1.   DEFINITION OF TERM. The Term of this Agreement shall commence
on the date hereof and shall continue throughout the term of Stockholder's
employment with the Company under the Employment Agreement of even date
herewith among Buyer, the Company and Stockholder (the "Employment
Agreement") and for a period following the termination of Stockholder's
employment under the Employment Agreement equal to either (A) 18 months, in
the event that Stockholder's employment under the Employment Agreement
terminates for any reason at any time prior to the second anniversary of the
date hereof or (B) 12 months, in the event that Stockholder's employment
under the Employment Agreement terminates for any reason (including
termination of the Employment Agreement in accordance with its terms) at any
time from or after the second anniversary of the date hereof (the "Term");
provided, however, that (i) under no circumstances shall the Term of this
Agreement extend beyond the fifth anniversary of the date hereof and (ii) in
the event of a Change of Control (as defined in the Employment Agreement) of
Buyer, if Stockholder's employment under the Employment Agreement is
terminated without Cause or pursuant to a Constructive Termination (each as
defined in the Employment Agreement) following such Change of Control, then
the Term of this Agreement shall terminate immediately.

         2.   AGREEMENT NOT TO COMPETE. As a condition to the transactions
being completed as of the Effective Time pursuant to the Merger Agreement,
and as a means reasonably designed to protect the intellectual property,
confidential and proprietary information concerning the Business during the
Term, Stockholder will not, without the prior written consent of Buyer,
directly or indirectly, engage in, assist (financially or otherwise),
associate with, or perform services (other than on behalf of Buyer or any of
its Affiliates) in any Restricted Business (as hereinafter defined),
including, without limitation, whether such engagement, assistance,
association or performance is as an individual, principal, officer, director,
consultant, advisor, proprietor, employee, partner, stockholder or other
investor (other than as a holder of less than one percent (1%) of the
outstanding capital stock or other equity interest of or in any corporation
or other business enterprise, provided that Stockholder's participation
therein is solely as a passive investor and does not include any role as
director, officer, manager or other service provider), creditor, guarantor,
agent, sales representative or other participant. For purposes of this
Agreement, "Affiliate" shall mean any person, partnership, limited liability
company, joint venture, trust, corporation or other entity, directly or
indirectly, controlling, controlled by or under common control with such
person, partnership, limited liability company, joint venture, trust,
corporation or other entity. For purposes of this Agreement, "Restricted
Business" shall mean (a) the Business together with any other business or
industry being considered or proposed to be conducted or engaged in by the
Company as of the date of this Agreement and (b) the business of Amazon.com,
Toys R Us and iVillage, together with any of their respective subsidiaries,
Affiliates or related parties. For purposes of clarification, "Restricted
Business" shall not

                                     -2-

<PAGE>

include the business of any entity that is engaged principally in the
healthcare industry, notwithstanding the fact that such entity may be
incidentally or insubstantially involved in any Restricted Business.

         3.   NON-INTERFERENCE. During the Term, Stockholder will not,
without the prior written consent of Buyer or any of its Affiliates,
directly, indirectly or as an agent on behalf of or in conjunction with any
person, firm, partnership, corporation or other entity (a) solicit, encourage
the resignation of, or in any other manner seek to engage or seek to employ,
any person who is as of the Effective Time, or within the prior three (3)
months had been, an employee of Buyer, the Company or any of their
Affiliates, whether or not for compensation and whether as an officer,
employee, consultant, adviser, independent sales representative, vendor,
independent contractor or participant, or (b) contact, solicit or service, in
connection with the operation of any Restricted Business, any person or
entity with whom Buyer, the Company or any of their Affiliates have a former,
current or prospective (as of the Effective Time) business relationship or
who is or was at any time during the Term a customer or client of Buyer, the
Company or any of their Affiliates, or a prospective (as of the Effective
Time) customer or client to which Buyer, the Company or any of their
Affiliates have made a business proposal.

         4.   CONFIDENTIALITY. Stockholder agrees not to disclose, use,
transfer or sell any intellectual property, confidential or proprietary
information concerning the Business, whether Stockholder has such information
in his or her memory or embodied in writing or other physical form, unless
such activities are on behalf of Buyer, the Company or any of their
Affiliates. For purposes of this Agreement, the phrase "intellectual
property, confidential or proprietary information concerning the Business"
means all information concerning the business, affairs, products, suppliers,
customers or employees of, or relating to, the Business, including, without
limitation, that which relates to marketing or brand recognition matters,
such as logos, typestyles, copyrights, trade names, brand names, user names,
service names, service marks and trademarks, or to technical matters, such as
patents, designs, drawings, specification sheets, schematics, test data,
technical literature, manufacturing and process information, know-how, trade
secrets, in process research efforts and technical data of Buyer, the Company
or any of their Affiliates, or to business matters such as the identity of
suppliers, customers or business partners or terms of business relationships
with suppliers, customers or business partners. The phrase "intellectual
property, confidential or proprietary information concerning the Business"
shall not, however, include any information to the extent that (i)
Stockholder is required to disclose any of the foregoing pursuant to the
provisions of applicable law; (ii) any such information becomes generally
known and available to the public otherwise than by reason of a disclosure or
communication of such information by Stockholder; or (iii) any such
information is disclosed after the written approval of Buyer, the Company or
any of their Affiliates. Stockholder agrees that the restrictions contained
in this Section 3 shall continue to apply without time restrictions, so long
as any information remains intellectual property, confidential or proprietary
information concerning the Business.

         5.   CONSIDERATION. Stockholder acknowledges that the consideration
for the covenants in Sections 2, 3 and 4 consists of substantial economic
value to be provided to Stockholder pursuant to the Merger Agreement, and
that no separate consideration shall be payable pursuant to this Agreement.
Stockholder also acknowledges that Buyer would not consummate the Merger
unless Stockholder entered into this Agreement.

         6.   MISCELLANEOUS.

              6.1   ENTIRE AGREEMENT; AMENDMENTS. This Agreement and any
document referred to herein or executed contemporaneously herewith set forth
the entire understanding of the parties relating to the subject matter hereof
and supersede all agreements, representations, warranties, statements,
promises and understandings, with respect to the subject matter hereof. None
of the terms or provisions hereof shall be modified or waived, and this
Agreement may not be amended or terminated, except by a written instrument
signed by the party against which modifications or waiver or amendment or
termination is to be enforced. No waiver of any one provision shall be
considered a waiver of any other provision, and the fact that an obligation
is waived for a period of time or in one instance shall not be considered to
be a continuing waiver.

              6.2   REMEDIES NOT EXCLUSIVE. No remedy conferred by any of the
specific provisions of this Agreement is intended to be exclusive of any
other remedy, and each and every remedy will be cumulative and will be in
addition to every other remedy given hereunder or now or hereafter existing
at law or in equity or by statute or otherwise. The election of any one or
more remedies will not constitute a waiver of the right to pursue other
available remedies.

              6.3   NOTICES. All notices under this Agreement will be in
writing and will be delivered by personal service or telegram, telecopy or
certified mail (if such service is not available, then by first class mail),
postage prepaid, to such address as may be designated from time to time by
the relevant party, and which will initially be as set forth below. Any
notice sent by certified mail will be deemed to have been given three (3)
days after the date on which it is mailed. All other notices will be deemed
given when received. No objection may be made to the manner of delivery of
any notice actually received in writing by an authorized agent of a party.
Notices will be addressed as follows or to such other address as the party to
whom the same is directed will have specified in conformity with the
foregoing:

              (i)   If to Buyer:

                    eToys Inc.
                    3100 Ocean Park Boulevard, Suite 300
                    Santa Monica, CA  90405
                    Attention: Chief Financial Officer
                    Telephone No.:  310-664-8100
                    Telecopy No.:  310-664-8101

                    with a copy to:

                    Irell & Manella LLP
                    333 South Hope Street, Suite 3300
                    Los Angeles, California 90071
                    Attention:  Anthony T. Iler
                    Telephone No.:  (213) 620-1555
                    Telecopy No.:  (213) 229-0515

              (ii)  If to Stockholder:

                    Matthew Glickman
                    309 Emerson Street
                    Palo Alto, CA  94301

              6.4   EQUITABLE RELIEF; ACCOUNTING. Stockholder acknowledges
that the covenants contained in Sections 2, 3 and 4 hereof are reasonable and
necessary to protect the legitimate interests of Buyer, that any breach or
threatened breach of such covenants will result in irreparable injury to
Buyer and that the remedy at law for such breach or threatened breach would
be inadequate. Accordingly, in the event of the breach by Stockholder of any
of the provisions of this Agreement, Buyer, in addition and as a supplement
to such other rights and remedies as may exist in its favor, may apply to any
court of law or equity having jurisdiction to enforce this Agreement, and/or
may apply for injunctive relief against any act that would violate any of the
provisions of this Agreement (without being required to post a bond).
Stockholder further understands that monetary damages will not be sufficient
to avoid or compensate for a breach of the covenants contained in Sections 2,
3 and 4 hereof and that injunctive relief would be appropriate to prevent any
such breach or threatened breach. Such right to obtain injunctive relief may
be exercised, at the option of Buyer, concurrently with, prior to, after, or
in lieu of, the exercise of any other rights or remedies that Buyer may have
as a result of any such breach or threatened breach. In addition, Stockholder
shall account for and pay over to Buyer all compensation, profits and other
benefits inuring to Stockholder's benefit that are derived or received by
Stockholder thereof resulting from any action or transaction constituting a
breach of the covenants contained in Sections 2, 3 and 4 hereof.

              6.5   THIRD-PARTY BENEFITS. None of the provisions of this
Agreement will be for the benefit of, or enforceable by, any third-party
beneficiary.

              6.6   SUCCESSORS AND ASSIGNS. This Agreement will be binding
upon and inure to the benefit of the parties, their respective successors and
permitted assigns. None of the parties hereto may assign any of their rights
or obligations under this Agreement without the prior written consent of all
other parties hereto, except that this Agreement may be assigned by Buyer to
any corporation or other business entity that succeeds to all or
substantially all of the business of Buyer through merger, consolidation,
corporate reorganization or by acquisition of all or substantially all of the
assets or capital stock of Buyer.

              6.7   GOVERNING LAW. All questions with respect to this
Agreement and the rights and liabilities of the parties shall be governed by
the laws of the state of California, regardless of the choice of law
provisions of that state or any other jurisdiction.

              6.8   RULES OF CONSTRUCTION.

                    6.8.1  HEADINGS. The Section headings in this Agreement
are inserted only as a matter of convenience, and in no way define, limit,
extend or interpret the scope of this Agreement or any particular Section.

                    6.8.2  TENSE AND CASE. Throughout this Agreement, as the
context may require, references to any word used in one tense or case shall
include all other appropriate tenses or cases.

                    6.8.3  SEVERABILITY. The validity, legality or
enforceability of the remainder of this Agreement will not be affected even
if one or more of the provisions of this Agreement are held to be invalid,
illegal or unenforceable in any respect. Further, if the period of time, the
extent of the geographic area or the scope of the prescribed activities
covered by this Agreement should be deemed unenforceable, then this Agreement
shall be construed to cover the maximum period of time, geographic area and
scope of prescribed activities (not to exceed the maximum time, geographic
area or scope set forth herein) as may be valid under applicable law. The
parties specifically intend that any court determining the extent of the
enforceability of this Agreement shall, if it determines that the Agreement
is not fully enforceable in accordance with its terms, modify the period of
time, geographic area or scope of prescribed activities provided for herein
to the minimum extent necessary such that the provisions hereof as so
modified are enforceable.

              6.9   ATTORNEYS' FEES. If any action or proceeding is brought
to enforce or interpret any provision of this Agreement, the prevailing party
shall be entitled to recover as an element of its costs, and not its damages,
reasonable attorneys' fees and costs incurred in connection with such action
or proceeding.

              6.10  COUNTERPARTS. This Agreement may be executed
simultaneously in two or more counterparts, each of which will be deemed an
original, but all of which together will constitute one and the same
instrument.
